Subject: [PATCH 1/2] submodule.c: convert submodule_move_head new argument to object id
Date: Wed,  5 Sep 2018 16:19:51 -0700
Message-ID: <20180905231952.28145-1-sbeller@google.com> (raw)

All callers use oid_to_hex to convert the desired oid to a string before
calling submodule_move_head. Defer the conversion to the
submodule_move_head as it will turn out to be useful in a bit.
